DUST-REMOVING ASH-SIFTIER HOUSING.

Application filed January 29. 1921. Serial No. 440,890.

To all whom t may concern Be it known that I, ROBERT LIND, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Dust-Removing Ash-Sifter Housings, of which the following is a specification.

This invention has for its object to provide improved means for so housing an ashsifter and an ash barrel, or other receptacle supporting the sifter, that the lighter ashes or dust liberated by the sifting operation will be conducted away without constituting a nuisance.

The invention is embodied in the improvements hereafter described and claimed. n

Of the accompanying drawings forming a part of this specification?.-

Figure 1 is a front elevation of an ashsifter housingembodying the invention,

Fig. 2 is a section on line 2--2 of F1gure 1.

Figure 3 is a section on line 3--3 of Figure 2.

The same reference characters indicate the same parts in all of the figures.

In carrying out my invention I construct, preferably from sheet metal, a casing comprising a lower portion adapted to bear upon a floor and to enclose an ash sifter 12 and an ash barrel 13, or other receptacle for ashes falling from the Sifter, and an upper portion constituting a flue located above and communicating with the lower portion, the sifter surmounting the receptacle.

In the preferred embodiment of the invention here shown, the casing includes two vertical side walls 14, the upper portions of which are tapered, a back wall 15, an inclined upper front wall portion 16, and a lower front wall portion, formed a door 17, hinged at 18 to one of the side walls. The inclined front wall portion 16 forms the front of a flue, the sides of which are formed by the tapered upper portions of the side walls 141. The sifter and receptacle-enclosing lower portion includes all of the casing below the said inclined front wall portion and tapered side wall portions.

The inclination of the front wall portion 16 is such that its lower end is over the door 17, and its upper end joins the upper end of the back wall 15. I prefer to provide the front wall portion 16 with a section 16il hinged at 20. The lower edge of the inclined front wall portion forms the upper margin of a restricter opening 21, the lower margin 0f which is formed by the upper edge of the door 17. Said opening coincides with the ash-sifter when the latter is positioned in the casing and is above the space enclosing the receptacle 13, and extends across the front of the casing, and is formed and arranged to not only permit a concentrated flow of air across and above the sifter 12, but also to permit manipulation of the sifter. By manipulation I mean the insertion, removal, and agitation of the sifter. The upper end of the casing is provided with an outlet 23 for dust-laden air, said outlet being preferably a short tube or pipe fixed tol and projecting rearward from the upper end portion of the back 15, and adapted to enter an opening formed for its reception in a chimney 24, and provided with a damper 25, having a handle 26 projecting through one of the side walls, whereby the damper may be opened and closed. With the exception of the opening 21 and the outlet 23, the casing is closed and dust tight.

. A receptacle and an ash sifter being inserted in the lower portion of the casing,

the door 17 being closed and the damper 25 opened, a ilow of air is induced through the inlet 21, and through dust rising fromy the sifter, to the outlet 23, so that the dust is carried to the chimney.

The inlet opening 21 is so formed and arranged that the operator may conveniently operate the sifter. The hinged section 16a when displaced, permits the convenient insertion and removal of the sifter, the recep tacle 13 remaining in the casing. When the receptacle is filled, the door i7 may be opened to permit its convenient removal. Vhen the sifter is not in use, the damper 25 may be closed, to prevent interference with the draft of the chimney through a stove or furnace connected elsewhere with the chimney.

The casing formed as shown by the draw ings, constitutes a lean-to, having a vertically elongated inner face, adapted to bear against one side of a chimney. It will now be seen that the invention is embodied in an elongated casing formed to bear at one end on a floor, with its major axis upright, said casing including a base portion constituting a receptacle for an ash barrel and a sitter mounted thereon, and an upper portion constituting a hue communicating with the receptacle. The essential members of said casing are the elongated upright back member 15 forming the back of the reeep tacle and of the Hue and provided with an outlet 23 projecting rearward from its upper end portion, side members 14 forming the sides of the receptacle and of Vthe flue, a door 17 forming the fronty ofthe receptacle,` Aand afrelatively yshort lfront member formingr the frnt'of' the flue and having its lower -"end spaced above the upper. lend oi the door to form an r air inlet 21. The inclinationot the said front member and of the lorwardedges of the upper portions of the side nien'ib'crs let ycauses the flue to converge yupwardly from the inlet 2l to the outlet '23, so that air entering the inlet ismdrawn forcibly to the Loutletand carries withit dust rising from'theA sitter-,the upward movement of the air and dust being accelerated by the convergence of the -Hue.

I claim: ,n y

l. An elongated casing formed to bearat one end o n a floor with its major axis upright, including a base portion constituting a `barrel andsiiter recept/acle,'and an upper portion constituting ya "flue communicating with the receptacle, said casing comprising an elongated uprightlback member forming l ythebzftjcl of the receptacle and of the iue,

and providedivith V`an'outlet in its upper end portion, side members forming the sides of vthe receptacle and of the flue, `a 'door forming the frontiof the receptacle, anda relatively sliort front member forming the front oi the flue'and having its lower end spaced above the -upper `end, of said door toiorm an air inlet, said Jfront member and the forward edges oi the upper portions of the side members'being inclined to cause an upward convergence of the ue, and accelerate the movement of air entering said inlet, the said outlet being extended rearwardly from the upper end of the back member and adapted to enter an opening in a chimney be'side which the back member is located. p

2. An elongated casing formed'to bear at one end on a floor with its major axis upright, including a base portion constituting a .barrel and sitter receptacle, 'and an upp'erportion lconstituting a lueic'om'm'unicating with the receptacle, said easing comprising an elongated upright back `m`ember forming the bach of the 'receptacle and of the flue, an'd'provided with an outlet yin its upper vend portion, sidefm'embers forming the sides' ofthe receptacle 'an'd'ofthe flue, ado'or forming the front of the receptacle, and 'a relatively I short vfront member 'forming the front of the flue vand having its lower end spaced above the upperfend of saiddoor to form an air inlet, said front member an'd'theforward edges ofthe upper pbi'tionsof the side members beinginclined to Cause'an upward convergenceof the Hue,v and accelerate the movement of'air entering said inlet, the said outlet 'being extended rearwardly from'the upper 'end of the back member and adapted to enter an opening in a chimney beside which the backn member is located, the lower portion ofsaid inclined member being a hinged section adapted to'be displaced to iacilitate"access to barrel and sitter in'said receptacle.

ln testimony whereof I have alixe'dmv signature.

ROBERT LIND.
